+SYNOPSIS
+========
+
+dis6502 [*-b* | *-l* | *-c* | *-r <address>*] [*-a*] [*-p <pfile>*] [*-v <address>*] [*-7*] *file*
+
+DESCRIPTION
+===========
+
+Dis6502 disassembles 6502 binary files. Binary formats understood include
+Atari binary files (L menu command) and boot files. Equate and control
+files can be included via the option to name well known locations and to
+control the disassembly process. The output includes a cross reference.
+
+The disassembly process is a two pass operation: First the program flow
+is traced starting with the init and run parameters in the file headers.
+The dump routine then prints out the information.
+
+OPTIONS
+=======
+
+**-r** *<address*>
+  *file* is raw binary, located at *<address>*.
+
+**-b**
+  *file* is an Atari boot image (disk or cassette). Note that neither .ATR
+  nor .CAS images are supported: the file must be a raw image with no header
+  information. For disks, this is called an XFD file.
+
+**-l**
+  *file* is an Atari load file (aka XEX).
+
+**-c**
+  *file* is a Commodore 64 executable.
+
+**-a**
+  Generate assembly output. Suppresses the addresses and object
+  code normally printed on each line of output, and omits the
+  cross-reference section from the end of the output.
+
+**-p** *<pfile>*
+  Use predefinition file. See **FILE FORMAT** for the predef file format.
+  Up to 10 **-p** options may be included.
+
+**-v** *<address>*
+  Alternate vector address (normally **$FFFA**). This option only has
+  any effect with raw binaries (**-r** option).
+
+**-7**
+  Mask character data to 7-bit.
+
+FILES
+=====
+
+**/usr/share/dis6502/atari8.predef**
+
+**/usr/share/dis6502/c64.predef**
+
+Predefinition files for Atari 8-bit and Commodore 64, containing the usual
+system equates.
+
+FILE FORMAT
+===========
+
+Lines in a predefinition file consist of:
+
+**label** .eq *address*
+
+**label** .equ *address*
+
+  Defines a label. The **.eq** and **.equ** forms are equivalent.
+
+**.jtab2** *lowaddr,hiaddr,count*
+
+  Defines a table of *count* pointers, split into low and
+  high byte tables. In assembly code, such a table might look like::
+
+    ; func1, func2, func3 are addresses.
+    table_lo: .byte <func1, <func2, <func3
+    table_hi: .byte >func1, >func2, >func3
+
+  To disassemble these, assuming the address of *table_lo* is **$1000**,
+  use::
+
+    .jtab2 $1000,$1003,3
+
+**.rtstab** *lowaddr*\,*hiaddr*\,*count*
+
+  Like **.jtab2**, but each entry contains the target address minus one, for use with RTS.
+
+**.trace** *address*
+
+  Causes the trace process to continue at *address*.
+
+**.stop** *address*
+
+  Causes the trace process to stop at *address*.
